IMPROVEMENT IN CULTIVATORS AND HARROWS COMBINED.

Specification forming part of Letters Patent No. 163,523, dated May 18, 1875; application filed I February 13, 1875.

To all 'whom it may concern:

Be it known that I, ELIAS M. POTTER, 0f Rutherford Depot, in the county of Gibson and State of Tennessee, have invented a new and valuable Improvement in Cultivator and Harrow; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of aside view of my cultivator and harrow, and Fig. 2 is a plan view of the same.

This invention has relation to means for cultivating and harrowing the soil at the same time; and it consists in combining with a plowstock, carrying a gang of plows, a triangular harrow, open in the rear, and connected to the said stock by means of pivot and steady pins, as will be hereinafter explained.

In the annexed drawings, Figs. 1 and 2, I have represented three light turn-plows, which are arranged in a gang, and secured to a stock consisting of three beams, A A A, connected together at suitable distances apart by means of end pieces A, and provided with handles B B. The standards O of the plows are perpendicular to the stock, and they are secured to their respective beams composing this stock by means of screw-threaded staples a and nuts I). The frontedges of the standards 0 are notched, as shown in Fig. 1, to receive the upper limbs of the staple-fastenings a, and prevent the standards from slipping.

In combination with the gang of plows,

above described, I use a harrow, the teeth 0 c of which are secured to forwardly-converging beams D D. This harrow is connected to the middle beam of the plow-stock by means of a vertical pin, 0, which is long enough to allow the necessary vertical play of the harrow when the machine is in operation, and which also allows the harrow to vibrate laterally. The harrow-beams are not connected together in rear, and they are prevented from receiving undue lateral vibration by means of extensions c c of the two front teeth c rising in rear of the rear cross bar A of the plowstock. By these means the driver can walk between the harrow-beams, and conveniently control the plow by its handles, and the harrow-beams can be made any desired length without interfering with the legs of the driver walking between them.

I may use a double-tree or a single-tree, and attach the same to a draft-eye, f, or to an adjustable segment-shaped clevis, k, as shown.

hat I claim as new, and desire to secure by Letters Patent, is-

In combination with the plow-stock A, the triangular harrow, loosely connected by means of the pin 6, and limited in lateral vibration by the steady-pins 0 0 substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

E. M. POTTER.
